Problem Cause/Solution
Power LED does
not light up when
the power is
switched on.
Mains voltage not connected.
► Check voltage of electrical outlet.
► Check fuse at underfloor heating
controller.
LEDs 1...8 of the
zones do not illumi-
nate green continu-
ously during start-
up.
The room name is not assigned.
► Check whether or not the Hometronic
Manager is installed.
► Check whether or not a room name is
assigned to zone.
► Check the antenna connection.
► Reassign the zone, if applicable.
LEDs 1...8 of the
zones do not illumi-
nate red continu-
ously during start-
up.
The setpoint adjuster cannot be as-
signed.
► Check whether or not batteries in
setpoint adjuster are inserted prop-
erly.
► Check wireless connection.
► Check the antenna connection.
Rooms are not
heated/cooled.
► Check heating and inlet temperature.
► Check adaptation to thermal actuator
(see Page 6).
► Check fuse of underfloor heating
controller.
If fuse is defective:
► Check actuators for short circuit.
► Change the fuse.
The LED lights up
red after commis-
sioning.
There is a fault in one of the tempera-
ture zones (see Page 12).
► Check wireless connection.
► Check the antenna connection.
► Check whether or not zone is as-
signed correctly.
► Check the batteries of the allocated
devices.
Room controlled
incorrectly.
► Check whether or not adjustment dial
of setpoint adjuster is at position 0.
► Check whether or not the adjusting
ring can be turned between -12 and
+12 with the housing cover removed.
► Check whether or not a setpoint
adjuster is assigned to room.
The LED flashes
rapidly.
No device installed.
► Install the devices again.
The LED flashes.
No antenna connected or antenna
defective.
► Check whether or not an antenna is
connected.
If no antenna is connected:
► Connect an antenna.
If an antenna is connected:
► Check the antenna connection.
► If applicable, replace the antenna by
a new one.
